Nice #s, ecpecially through an auto. What was your peak trq? I think that is more then 480fw, I'm thinking closer to 500 if not a little more, since autos eat more.

Hows about a dyno graph posted?? I'm interested in the power/torque curve of this thing since I have the "little brother" and may upgrade by the end of the year.

Thanks everybody!

I`m getting ready to go to work so i`ll answer most ofthe questions and try and post the graph this weekend.

These are SAE corrected. I made 3 pulls first was 391.9, 2nd 403.7, and third 395.6. 2 weeks ago I only dynoed 366 but got a reflash and changed the exhaust around a little.

Because of the stall and possibility of downshift the dynoshop did not want to hit it very early, my grapgh starts at 4300rpm past my peak torque. So i don`t really know my peak torque numbers.
max horse power was at 6150rpm.

here`s a sample of the graph as best as I can tell, 4500rpm=275hp,340tq, 5000rpm325hp, 346tq, 5500rpm=355hp, 348tq, 6000= 380hp, 346tq, 6150rpm 403hp, 345tq

I wish I could have seen peak torque but it was flat.

GREAT #s!!! Cutout? What size TB are you using? Is that the high lift or regular lift cam?

That's making some power. What kind of exhaust do you have and who did the programming? I am hoping my 355 can come close to that and that was with the converter locked right?

From those few #s you gave us it looks like you have a very flat trq "curve".

here`s some answers to your questions:

max power was at 6150rpm the a\f started to get a little fat above this.

cam is XE230/236 112 lobe sep lift w\ 1.6 rockers is .544in/.555exh

52mm AS&M TB

SLP 94-95 style headers off road pipe, magnaflow catback

Ed wright tuning, same as Ken95z28.

Next year I am getting LT1 edit for OBD2 and going to Carolina automasters for a dynotune. Mainly to smooth out the idle its rich, and clean it up a little over 6k. I`ll also be getting a different pcm. After my build this year i ran out of money and since i already had Ed wright tuning for my bolt-on car, it only cost me 150 for the reflash, and the second one after the wideband was free.

I will try and get the dynograph posted soon.

Stalls eat horsepower, right?
